Market Power versus Efficiency Effects of Mergers and Research Joint Ventures: Evidence from the Semiconductor Industry

NBER Working Paper No. 10323Issued in February 2004NBER Program(s): IOPR

Merger control authorities may approve a merger based on a so-called 'efficiency defence'. An important aspect in clearing mergers is that the efficiencies need to be merger-specific. Joint ventures, and in particular research joint ventures (RJVs), may achieve comparable efficiencies possibly without the anti-competitive (market power) effects of mergers. We present evidence for the semiconductor industry that RJVs indeed represent viable alternatives to mergers. We empirically account for the endogenous formation of mergers and RJVs.
